Multiple Choices (chose the correct or
the best answer)

1.Which of the following best defines a mineral and a rock?

A) A rock has an orderly, repetitive,
geometrical, internal arrangement of minerals; a mineral is a lithified or
consolidated aggregate of rocks.

B) A mineral consists of its constituent
atoms arranged in a geometrically repetitive structure; in a rock, the atoms
are randomly bonded without any geometric pattern.

C)
In a mineral the constituent atoms are bonded in a regular, repetitive,
internal structure; a rock is a lithified or consolidated aggregate of
different mineral grains.

D) A rock consists of atoms bonded in a
regular, geometrically predictable arrangement; a mineral is a consolidated
aggregate of different rock particles.
